Designing antennas for the aperture array SKA-low instrument; a system perspective

Abstract

This paper describes the important design aspects of an array antenna for the low frequency instrument of the SKA telescope (SKA-low). The most important considerations to meet the telescope performance requirements are discussed. Finally, a plot of the expected sky brightness sensitivity for phase I of the SKA using log-periodic antennas is presented. Keywords-radio astronommy; log-periodic antenna; system designI.
